Specification of Letters Patent.

Patented Dec. 11, 1917.

To all whom it may concern.

Be it known that We, HARRY KAUFMAN and FRANK M. KAUFMAN, citizens of the United States, residing at Philadel hia, county of Philadelphia, and State of ennsylvania, have invented certain new and useful Improvements in Woven Pile Fabrics, of which the following is a specification.

Our invention relates to improvements in Woven pile fabrics, the object of the invention belng to provide a cut pile fabric, in which the War ile threads which form the tufts of the fa ric are firmly secured in the backing, and are so uniformly positioned as to resent a smooth surface.

further object is to provide a woven pile fabric in which the tufts are formed by war pile threads in banks of six, each bank d1- Vided into two series of three pile threads, and with the alternate pile threads in any series extendin in the same direction from one backing fa ric to the other, and the adjacent pile threads extending in opposite directions, and the corresponding pile threads of the adjacent series oppositely po sitioned.

.A further object is to improve upon the fabric disclosed in Patent No. 1,169,835, granted to us February 17th, 1916.

- With these and other objects in view the invention consists in certain .novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings:

Figure 1 is an exaggerated view in longitudinal section, pile fabric.

Figs. 2, 3, 4:, 5, 6, and 7 are. views similar to F1 1, each view showing but one pile threa connecting the backing fabric, and

Fig. 8 is a diagrammatical plan view of cut.

bottom backing fabrics X tively, which are connected threads, 1, 2', 3, and 1", 2,

and Y respecywarppile and 3 respectively. These reference characters are used to indicate that the pile threads are formed in banks of six threads each, each bank" divided into two series of .three thread's'each, with the threads of each series in the same bank oppositely disposed, as will be more fully tt hereinafter explained.

illustrating our improved tioned over weft thread A, thence own We would have it understood that we mean by the term series of three threads to refer to a group of three pile threads, which are successively placed transversely of the fabric and are separated, or set off from the other threads by a'binding warp thread.

The top backing fabric X consists of binding Warp threads 6 and 7, and weft threads A, B, C, D, E, and F, woven between the binding Warp threads 6 and 7. The lower backing fabric Y consists of binding warp threads 4 and 5 with weft threads A, B,

C, D, E and F woven therein.

The upper and lower picks of the weft threads are simultaneously woven by the shuttles, and hence for convenience of description, these pairs of picks of the weft threads are given corresponding letters,'the reference letters of the picks of the bottom fabric bein primed as described.

While F 1g. 1 illustrates two binding warp threads in both upper and lower fabrics, it

is to be understood that but a single binding C, thence downwardly under weft thread D, over weft thread E, and under weft thread F of the lower backing fabric Y.

- A shown in Fig. 3, pile, thread 2 is osiunder weft thread B, over weft thread C, under weft thread D, thence up to and over weft thread E and under weft thread F.

Fig. 4 shows the position of pile thread 3 which passes first over weft thread A, thence under weft thread B, thence up to and over weft thread C, underweft thread D, over weft thread E, and under weft thread F.

Figs. 5, 6 and 7 show the positions of pile threads 1*, 2, and 3, which it will be noted are directly opposed to the positions or locationsof the pile threads 1, 2 and 3.

Tracing out these pile threads 1, 2? and 3?, we find n Fig.5, thatgiilje thread 1 first passes under weft three. A, thence over thence down to and weft thread B, thence under weft thread C, thence up to an over -weft thread D,

under weft thread E, and over weft thread F A, thence over weft thread B, thence down to and over weft thread C, thence over weft thread D, thence under weft thread E, thence up to and over weft-thread F.

Having now traced the several threads of the pile, attention is directed to Fig. 1, which shows on an exaggerated scale, the locations of all of these threads, and it will be noted in this figure, (due to the fact that the pile threads of each series of three are oppositely disposed) that the corresponding threads of each series cross each other, but are woven in opposite directions as indicated by the arrow. When the fabric is cut along a center line between the two backing fabrics, the tufts will have a smooth appearance, and all threads will be uniformly tied in the backing fabrics.

Various slight changes might be made in the general form and arrangement of parts described without departing from our invention, and hence we do not limit ourselves to the precise details set forth, but consider ourselves at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having fully described our invention 'what we claim as new and desire to secure set off "from the other threads by a binding warp thread, the corresponding threads of each series oppositely disposed, and crossing fabrics.

the threads of each series successively placed transversely of the fabric and separated or set off from the other threads by a binding warp thread, the corresponding threads of each series opposltely disposed and crossing Byreference to Fig. 6, it will be seen each other at a point between the backing fabrics, and the adjacent pile threads of each series extending in opposite directions from one backing fabric to the other, while the alternate threads of each series extend in the same direction from one backing fabric to the other.

A pile fabric, comprising top and bottom backin fabrics, a bank of pile threads connecting the backing fabrics, each bank consisting of two series of three threads each, the threads of each series successively placed transversely of the fabric and separated or set off from the other threads by a binding warp thread, the corresponding threads of each series oppositely disposed and crossing each other at a point between the backing fabrics, said backing fabrics consisting of weft threads and binding warp threads, a filling shot or weft thread of each backing fabric located between each pair of pile threads, and said shots located in parallelism, one above the other, the said pile threads in both top and bottom fabrics woven with three of said shots, and a single binding warp thread in each backing fabric between each series of three pile threads.

4. A pile fabric, comprising top and bottom backing fabrics, a bank of pile threads connecting the backing fabrics, each bank consisting of two series of three threads each, the threads of each series successively placed transversely of the fabric and separated or set off from the other threads by a binding warp thread thereof, the corresponding threads of each series oppositely disposed and crossing each other at a point between the backing fabrics, and the adjacent pile threads of each series extending in opposite directions from one backing fabric to the other, while the alternate threads of each series extend in the same direction from one backing fabric to the other, said backing fabrics consisting of weft threads and binding warp threads, a fillingshot or.weft thread of each backing fabric located between each pair of pile threads, and said shots located in parallelism, one above the other, the said pile threads in both top and bottom fabrics woven with three of said names to this specification in the presence of two subscribing witnesses.
